[Limdep Nlogit List] Statistical significance value for the omitted/reference level in an effects coded model

hi NLOGIT team,

I am running an RPL model which I have effects coded.
The model output doesn't display the reference level's coefficient
so because this is effects coded, to get the coefficient of the reference
level, I use the negative sum of the other level's coefficients.
currently to calculate the standard error of the coefficient of the
reference level, I have to use the covariance matrix for each level of the
attribute to calculate the standard error for the coefficient of the
reference level.
Is there an easier way in the current NLOGIT output for me to do this or do
I just need to keep manually calculating this?
thanks for your help.
